The inlet pipes of the system installed on the VN and VHD truck models may crack or break, which could cause a fire as hot exhaust fumes heated engine parts.
Volvo Trucks said it was aware of a number of cases of heat damage. “In two cases these have led to a fire, though without any personal injury,” the company said.
Volvo Trucks would inspect and replace any damaged parts and also install a heat shield on all trucks. This work is estimated to take about an hour, it said.
